TANK.

T 0 ZZ whom it 'mag/ 'cozwewt:A A

Be it known that I',.RoERT 15. KUHN, a citizen' of the UnitedStates, residing at Canton, inthe county offStark `and State of Ohio, have invented certain new and useful Improvementsin. Tanks,.of which the f0llowing is a specification.

The invention relates to tanks forcarryingfgasolene andk other-liquid fuels in vautomobiles, motor trucks, motor boats, and like uses; and the object of .thefimprovement is to provide means 'for preventing a. draining of all .theliquid fuel from the tank through its ordinary-outlet, fand'to provide means for separating water and'yoth'er liquid or solid refuse fromlthe liquid. fuel, so that the same will not be.v carriedfinto, the'. dischargepipe.y These objects' are lattained by` providing an open sump ybelowthefbottom of the tank for receiving the water 'and other refus'e which settle from the liquid fuel; and by providing an ordinaryoutlet 'opening from the tank above its bottom, and an auxiliary outlet opening from .the'sumpv above its bottm, and a common discharge pipe leading from the outlets with a controlling valve at the junction thereof.

A preferred embodiment of the invention, thus outlined, is illustrated in the accompanying drawings, forming part hereof, in

which- Figure 1 is a side elevat1on. sect1on of the bottom portion of a tank showing the improvements applied thereto; Fig. 2, a fragmentary under side plan view of the same; and Fig. 3, a fragmentary bottom plan v1ew of the same.

Similar numerals refer to slmilar parts throughout the drawings.

The tank 1 is provided with the pendent sump 2 secured to the bottom of the tank and opening freely downward therefrom.

The three-way valve case 3 is provided at one side of "the sump, in which case is formed the pori; it opening downward from the tank, the port 5 opening from the side of the sump above the bottom thereof, and the port 6 communicating wlth the discharge pipe 7 y The valve 8 in the case 3 is provided with the port 9, which may lead either from the tank port 4 or thesump port 5to the discharge port 6 by a proper turning o`f the valve, or the valve may be turned to entirely close the discharge port.

The outlet from the tank 1s preferably Patented oet. 19, 1915.

formed by the stand pipe 10 rising from the tank port in the valve case, and having lts'upper end curved laterally-and `downward so that the receiving mouth 11 of the outlet is presented downward to require the liquid fuel to flow upward when entering the same; thus preventing undue agitation of the liquid fuel in the bottom of the tank,

so that the water andV other heavy refuse may settle therein.4 f

The sump port 5 forms van auxiliary outlet from the side of the sumpabove the bottom, and preferably extends laterally up-"f ward therefrom so that its receiving mouth l2 is 4directed downward 'to' require the liquid fuel to flow upward whenentering the' same; thereby preventing an agitation insthenf, I

bottom of the sump so that water and other,

. :i275 The deflecting `flange 13 is preferably proheavy refuse will settle therein.

vided inthe side of theA sump above theyl mouth 12 of the outlet port, for the purpose of requiring the liquid to flow downward toward the bottom of the sump before passing upward into the downwardly presented mouth of the outlet,` so that water and other refuse will more certainly sink to the bottom of the sump, whence it may be drawn off from time to time, by the pet-cock 14 leading therefrom. Y

In the use of the tank, the same being filled with gasolene or other liquid fuel, the valve 8 is turned so that its port 9 leads from the tank port 4 to the discharge port 6, in which relation of the parts the sump port 5 is closed, as shown in Fig. 1, of the drawings. The water and other compara tively heavv refuse contained in the liquid fuel. settle bv gravity to the bottom of the tank below thegnouth 11 of the outlet therefrom, and ultimately find their way into thebottom of the sump, so that only free liquid fuel will be drawn off through the outlet from the tank.

Then the level of the liquid fuel in the tank falls below the mouth of the 'outlet pipe therein, the tank may either be refilled, or the valve 8 may be turned so that the port 9 therein will lead from the sump port 5 to the discharge port 6, for drawing ofi' the remainder of the liquid fuel remaining in the bottom ofthe tank and the top of the sump, without drawing 0H the refuse which may have settled in the sump below its outlet.

It will be understood that inthe use of he tank,` is desir; ble to open the pet- .li from time to time, to draw ott' the aiment and Water as the same accumulates `rein, so that ordinarily there will be no at-ei' or refuse in the sump above the ,t rien it becomes necessary to dravv ott the unid fuel from the bottoni of the tank and of the sump, the same Will be substantially free from Water and refuse.
